If Karan and Teja stop with trying to protect one another, that might work in their benefit.
In the end.. Teja received one proper good feedback which will in the end influence her tone and attitude as well, which is sometimes listen also to others, even if you are convinced of you being right.. Benefit is in that part..
If she listens and understands, shows this then this could be visible in behavior.
I don't find Teja arrogant. She is just self confident and perhaps quickly bored with topics which she feels are not important or being over stretched. This could show as arrogant, especially when the topic is important to the other party.
I am surprised to see the number of posts for Teja... For someone supposedly does not impact the game very much.... 😂
